OK，安装pipeline插件。
管理詹金斯 ->管理插件-> 安装插件（pipeline）

一、项目内容

pipeline {
   agent { label 'jnlp-slave'}   //指定标签为jnlp-slave节点
    environment {
        DISABLE_AUTH = 'true'     //定义变量 DISABLE_AUTH
        DB_ENGINE    = 'sqlite'      //定义变量 DB_ENGINE 
    }

    stages {	    //阶段（相当于一个部门）
        stage('Build') {    //脚步（相当于一个部门中的人员数据库、架构、运维、安全）	
            steps {  //脚步内的步骤（职责人员执行自己负责的任务）
                echo "Database engine is ${DB_ENGINE}"
                echo "DISABLE_AUTH is ${DISABLE_AUTH}"
                sh 'printenv'
            }
        }
    }
}

再次构建
